The DynaPrep MDSF Medium Diameter Split Frame was designed with accessory modules that vastly expand its capabilities. Engineered to surpass anything available today, the DynaPrep MDSF translates this benchmark to maximum power in cold cutting portable weld prep machine tools. The core design principal is power combined with durability.
Rugged and highly portable, E.H. Wachs’ DynaPrep MDSF offers unmatched form tooling capability on heavy wall pipe, including difficult to machine high alloy materials. Designed for cutting, beveling, counterboring, flange facing and more, it’s available in eighteen standard models for nominal pipe sizes ranging from 2in – 72in O.D. (DN50-1800), with each model covering a generous 6in range. Sold as complete kits or individual components, the DynaPrep MDSF is available in your choice of pneumatic, hydraulic or electric drive.
E.H. Wachs DynaPrep MDSF split frame clamshell machine tools are the foundation of a complete machining system that performs a wide range of field machining applications, with accessory modules that expand its capabilities. DynaPrep pipe weld prep machine tools can perform precision inline pipe cutting, squaring of pipe ends, and destructive cutting of corroded or damaged pipe and pipelines.
A pipe cutter by definition, the DynaPrep MDSF pipe cutting machine can simultaneously cut and bevel inline pipe, and when equipped for pipeline applications can quickly prep thin wall and out of round piping. For machining of heavy wall pipe or high alloy materials, additional modules are available that mount without modification to the standard ring set.
Additionally, each MDSF can act as a pipe beveler, beveling inline pipe, open pipe ends and chamfering pipe and casing conductors. In applications where a compound bevel is required, the DynaPrep can act as a compound beveler, beveling with form tools (where the tooling has the finished profile) or single point machining complex preps such as J-prep bevels.
For counterboring pipe, the DynaPrep MDSF series of rotating lathe machine tools can be outfitted with counterbore modules, enabling counterboring and deep counterbore machining of pipe ends for tapers and transitions.
Going far beyond basic cut and bevel capability, the DynaPrep MDSF can be equipped with FFC and FFR modules for flange facing, converting the DynaPrep from a pipe cutter into a flange facer to face and resurface flanges, avoiding the need to bring specialized facers onsite. As a flange resurfacing machine, the DynaPrep MDSF can perform bolt face resurfacing, raised face resurfacing, record grooving, and RTJ ring groove creation and resurfacing.
